The Full Strawberry Moon arrives Sunday, and it will be a "supermoon" appearing larger than many other full moons.

A supermoon is a full moon that coincides with the moon's perigee, or the point in its orbit at which it's closest to Earth. While the nickname makes it sound extraordinary, supermoons actually occur every year.

They can appear more dramatic, however -- 14 percent larger and 30 percent brighter than when the moon is at apogee, furthest from Earth, according to EarthSky.org.

"These changes do not come all of a sudden from month to month, however, and without anything with which to compare them, the changes in the moon’s size or brightness are hard to quantify by simple observation," EarthSky adds.
